Trying not to let you in

Ive been hurt
More times then I can say
So I promised myself
I wont fall for another guy
Then you walked in my life
And I forgot everything
Im falling in love
Don’t know how to stop it
Im trying so hard
To not let you in
But when you look in my eyes
It gets you even closer
So I guess im going to have to tell you
I just have to be ready
To be broken once again
